Better package name for gRPC proto package #1189
Description
In #976, the proto's package was accidentally renamed from the already bad name v2 to the even worse name proto: ad074c8#diff-10f75d15f6edc72b2a60a954b02881a0239e0c384353b97e5f485d4a6f527469R9
This means that the example in examples/hooks/grpc doesn't work anymore because it's using the old v2 name.
In addition, for the next major release, I would like to rename the package to something more sensible. Maybe tusd?
